The SiBUC (Simple Biosphere including Urban Canopy) model uses &#8220;mosaic&#8221; approach to incorporate all kind of land-use into LSS. In the SiBUC model, the surface of each grid area is divided into three landuse categories and five components.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-525\" src=\"http:\/\/rwes.dpri.kyoto-u.ac.jp\/wp\/wp-content\/uploads\/2015\/11\/Sibuc-scheme.png\" alt=\"Sibuc scheme\" width=\"400\" height=\"261\" srcset=\"https:\/\/rwes.dpri.kyoto-u.ac.jp\/wp\/wp-content\/uploads\/2015\/11\/Sibuc-scheme.png 400w, https:\/\/rwes.dpri.kyoto-u.ac.jp\/wp\/wp-content\/uploads\/2015\/11\/Sibuc-scheme-300x196.png 300w\" sizes=\"auto, (max-width: 400px) 85vw, 400px\" \/><\/p>\n<p>Figure: \u00a0Schematic image of the land surface scheme (SiBUC).\u00a0Model structure and prognostic variables are shown.<\/p>\n<ol>\n<li>green area (vegetation canopy, ground)<br \/>\nThis is a natural land surface area (forest, grassland, bare soil, etc.), and it is usually treated in most LSS. For the vegetation scheme, SiB is adopted. Some modification from original SiB was done.<\/li>\n<li>urban area (urban canopy, urban ground)<br \/>\nThis is an artificial impermeable surface (buildings, houses, pavement, etc.). A new urban canopy scheme which can account for complex structure of canyon geometry has been developed. Heat island phenomena can be expressed by this scheme.<\/li>\n<li>water body<br \/>\nThis is a inland water surface (ponds, rivers, lakes) or ocean surface. Diurnal\/seasonal variation of water temperature and evaporation is calculated depending on water depth.<\/li>\n<\/ol>\n<p>Owing to the field experiments such as the Lake Biwa Project, GEWEX\/GAME Project, paddy field and farmland irrigation\/drainage scheme is developed. Which enables us to treat not only the natural water cycle, but also artificial water cycle caused by human activity.<\/p>\n<h3 dir=\"ltr\">Estimation of the global distribution of energy and water budget<\/h3>\n<p>The 2nd Global Soil Wetness Project (GSWP2) is an ongoing environmental modeling research activity initiated by the Global Energy and Water Cycle Experiment (GEWEX). One of the most important goal of GSWP2 is to produce state-of-the-art global data sets of land surface fluxes, state variables and related hydrological quantities for 10-year period (1986-1995). These data sets will be utilized to clarify the mechanism of climate variability and abnormal weather and role of land surface processes on them. In addition to the baseline experiment and sensitivity experiments of GSWP2, SiBUC is run with irrigation scheme activated to estimate the global distribution of irrigation water requirement (Figure-2).
